Release Notes, April 27

New Features
* added grid 7 for opaque tiles, so they don't interfere with scenery - no more holding shift to place all the time!
* added grid 8 for overlays - fades & scenery can now be used either under or OVER opaque tiles
* added best time & best score to level preview in mission map
* level end stats now animate

Fixes
* fixed issue of 2x2 tiles being offset in the editor - if you placed any 2x2 scenery since the last release, please double check its position!
* fixed a bug in trackbot AI
* respawning in an obstacle is now handled

Bug Levels
Most bug levels are fixed, please delete yours if it is fixed.

Move lines with 'reverse' checked don't always go to the reverse position at the start of the level, and I have no idea when does it go there and when not. I tried making an unrelated bug level, which happened to require a block of tiles starting in the far away position, but it didn't, which means I couldn't even illustrate this another bug I was intending to.
